The mission went well, the target had been taken out and you were now on your way back to the evacpoint.

Problem: You weren’t actually part of the group going to evac. You were somehow irritated and 'blinded' by a flashbang you saw too late, causing you to stumble downstairs, hitting your head pretty hard.

Then laying on the floor you tried to reach out for assistance while getting up, maybe Ghost or Gaz would hear it?

Wait is that blood on my temple?
